How to Fix Blurry Photos — What Works and What Does Not

The Honest Truth About Blurry Photos

Sharpening tools can improve slightly soft images but cannot fix truly blurry ones. Here is what to expect:

What Sharpening Can Fix

• Photos that are slightly soft from lens issues
• Images that lost sharpness during resizing
• Scanned documents that look a bit fuzzy
• Photos from older/lower-quality cameras

What Sharpening Cannot Fix

• Motion blur from camera shake
• Completely out-of-focus images
• Heavy compression artifacts
• Extremely low resolution images

How Sharpening Works

Sharpening increases contrast along edges in the image. It does not add new detail — it makes existing edges more prominent.

The algorithm:

1. Detect edges (areas of contrast change)
2. Increase contrast at those edges
3. Light side gets lighter, dark side gets darker
4. Result: edges appear sharper

Best Sharpening Settings

Image Type	Amount	Tip
Portrait	20-40%	Light touch to avoid skin texture issues
Landscape	40-60%	More aggressive for fine details
Text/Document	60-80%	High sharpening helps readability
Already sharp	0-10%	Little to no sharpening needed

Prevention Is Better

• Hold the camera steady or use a tripod
• Use faster shutter speeds in low light
• Tap to focus on your subject
• Use burst mode and pick the sharpest frame
• Clean your camera lens
